Histidyl-tRNA Synthetase Urzymes: CLASS I AND II AMINOACYL tRNA SYNTHETASE URZYMES HAVE COMPARABLE CATALYTIC ACTIVITIES FOR COGNATE AMINO ACID ACTIVATION

Four minimal (119 - 145 residue) active site fragments of Escherichia coli Class II histidyl-tRNA synthetase were constructed, expressed as maltose-binding protein fusions, and assayed for histidine activation as fusion proteins and after TEV cleavage, using the (32)PP(i) exchange assay. All contain...
